We used Ali at http://www.alitangiertours.com/ for a 4 hour tour. He met us and returned us to the ship. Some driving, a good deal of walking. Very pleasant guy. A good tour. Just beware that you may end up at a rug store with what I would call mid-pressure as opposed to high-pressure to buy a rug. If you're not interested in rugs just let him know. In fairness my sister did buy 2 rugs. Bottom line I would recommend Ali.
